We could use unstack + DataFrame constructor + pivot. We can't pivot a Series object, so we reset_index first.

To fix duplicate column names, we could reformat column names by creating a MultiIndex object by combining original column name level 1 with the tuple index:

QUESTION

How to transfer (using Program instructions) custom SPL token from my own account to another user's wallet?

Asked 2022-Mar-10 at 16:02

This is my situation:

I have created a wallet

solana-keygen new
I have created my own custom SPL Token

spl-token create-token
Then I created an Account for this SPL Token

spl-token create-account
The SPL token is now in my wallet A

In the Solana Program, I would like to programmatically transfer the custom SPL token from Wallet A to Alice(user) wallet when certain conditions are met (for example, when Alice answered a quiz correctly, she will be awarded some custom SPL token).

How do I authorise the Solana Program to deduct from Wallet A (which I had created) and transfer the tokens to Alice wallet?

Please advise me how to go about doing this. Really appreciate this.

ANSWER

To transfer an SPL token within a program, your best option is to have wallet A owned by a program-derived address, and then your program can transfer the tokens from wallet A based on any logic it wants.

So first, transfer the ownership to your program-derived address:

What is a System vs. Token Account?

Asked 2022-Feb-25 at 13:03

Solana noob here.

I'm trying to understand PDAs and ATAs better and one thing I first want to understand is the difference between a System Account and A Token Account.

What types of data does each type of Account hold? Is one derived from another? Can a program have both types of accounts associated with it?

context: https://spl.solana.com/associated-token-account

...

ANSWER

Answered 2022-Feb-25 at 13:03

A system account is one that was created by the Solana system program. It is typical that these are often considered a wallet conceptually.

A Token account is an account that is "owned" by the Token program. This enables the Token program to update the information in that account, whereas if other programs try to modify the data execution will fail.

What data, if any, is in one of these program owned accounts it defined by the program that owns it.

Other notes:

Programs themselves are accounts that are owned by the BPFLoader program

You can discover what is what from the command line with: solana account ...

(see solana account --help for more options)

For example, on a Program account in devnet:

How to transfer custom SPL token by '@solana/web3.js' and '@solana/sol-wallet-adapter'

Asked 2022-Jan-29 at 21:02

Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.

I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.

How can you transfer SOL using the web3.js sdk for Solana?

How to transfer custom token by '@solana/web3.js'

according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:

Create a @solana/web3.js Transaction object and add instructions to it
Sign the transaction with the wallet
Send the transaction over a Connection

But i am having difficulty finding examples or documentation as to how to do step 1 and 2.

ANSWER

Answered 2021-Dec-06 at 13:51

So i found a way to do this, it requires some cleanup and error handling but allows for a custom token transaction via @solana/wallet-adapter.

How to send spl-tokens with Solana smart contract?

Asked 2022-Jan-06 at 02:48

I'm a beginner Rust/Solana Developer and wanted to ask if someone knows how to send a spl-token from an account when the account receives a SOL?

I read the https://docs.solana.com/ but i could not find anything about SPL transfers.

Example of Smart Contract: https://github.com/solana-labs/example-helloworld

Example:

Acc1 sends 0.1 SOL to a address and for that Acc1 receives 1 SPL-TOKEN from that address.

Simple explanation: I need a minting website for a token.

I would really appreciate some help, thanks!
